$dbname ='publication'; //modify these
$dbuser = 'username'; //variables
$dbpass = ''; //// to your installation
$appname = 'application name'; // and preference
mysql_connect($dbhost, $dbuser, $dbpass) or die(mysql_error());

Try this: Adding users to MySQL
试试这个：将用户添加到 MySQL
You need grant privileges to the user if you want external acess to database(ie. web pages).
如果您想从外部访问数据库（即网页），则需要向用户授予权限。

You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).
您很可能没有为 MySQL 服务器使用正确的凭据。您还需要确保您所连接的用户具有查看数据库/表的正确权限，并且您可以从网络拓扑术语 (localhost) 的当前位置进行连接。
